WAVELENGTH CONVERSION DEVICE AND RELATED LIGHT-EMITTING DEVICE THEREOF

WIPO Patent Application WO/2015/180630

A1

Provided is a wavelength conversion device (100), comprising a substrate (130), a reflecting layer (120), and a light-emitting layer (110) superimposed successively. The light-emitting layer (110) contains a wavelength conversion material and a second binder, and the reflecting layer (120) contains reflecting particles, auxiliary particles, and a first binder. The reflecting particles are used for reflecting light, and the auxiliary particles are used for filling voids between the reflecting particles. The first binder is used for binding the reflecting particles and auxiliary particles into a layer. The reflecting layer (120) not only ensures a higher reflectivity, but also achieves a lower thickness, such that the heat produced by the light-emitting layer (110) can be better transmitted to the substrate through the reflecting layer (120), which avoids a decrease in the light conversion efficiency caused by an excessively high temperature of the light-emitting layer (110). Also disclosed is a light-emitting device comprising such a wavelength conversion device (100).
